ARTAS

ARTAS (ATM suRveillance Tracker And Server) is a system designed by Eurocontrol in order to help in Aerial surveillance and Air traffic control. It can establish an accurate Air Situation Picture of all traffic over a well-defined geographical area (e.g. ECAC), and to distribute the relevant surveillance information to a community of user systems.

ARTAS users

A User of ARTAS in a general sense is defined in this context as any ATC subsystem having a requirement to receive at defined instants the best and most up-to-date estimate of all or selected aircraft state vector elements for all air traffic of interest to this User, e.g.:

• Operator Display System,
• Flight Data Processing System,
• ATC Tools,
• Flow-Control Management System,
• Sequencing and Metering system,
• Remote TMA’s,
• Military Units, etc.

ARTAS is a distributed system composed of a number of identical subsystems co-operating together. Each subsystem, called an ARTAS Unit, will process all radar data reports to form a best estimate of the current Air Traffic situation within a given Domain of Interest.

Adjacent ARTAS Units will co-ordinate their tracks to build a unique, coherent and continuous Air Situation Picture over the complete area.

ARTAS unit groups

Four groups of main functions are implemented in an ARTAS Unit:

• The TRACKER processes the radar input data and maintain the latest air situation represented in the Track Data Base.
• The SERVER carries out the Track and Sensor Information Services, i.e. the management of all requests from Users and the transmission of the relevant sets of track/sensor data to these Users, and the so-called inter-ARTAS co-operation functions
• The ROUTER BRIDGE handles the external interfaces to the Normal Users, the Broadcast Users, the Adjacent ARTAS Units and the surveillance sensors. It also implements the Radar Input Processing function.
• The SYSTEM MANAGER carries out the functions related to the supervision and management of the ARTAS Unit.
